What property do additives typically enhance in lubricants?

Additives in lubricants play a crucial role in enhancing their overall performance. They are carefully formulated to improve various characteristics of the lubricant, such as its viscosity, stability, and ability to reduce friction. By doing so, these additives ensure that the lubricant can withstand the specific conditions it will face during use, such as high temperatures, pressure, and contamination from external elements.

For instance, certain additives can prevent oxidation and corrosion, while others improve the lubricant's ability to maintain its consistency over wide temperature ranges. This ability to maintain performance under varying operational conditions is essential for the efficiency and longevity of machinery and equipment. Thus, the enhancement of performance is a primary reason for the inclusion of additives in lubricants, making this the correct choice in the context of the question.
